I saw that too... wasn't sure if I should e-mail them yet or not but I'm thinking about it :/ It's better than outright rejection I guess!
edit: I don't really know how graduate admissions work, but maybe they're seeing how many people bite on their offers from two weeks ago before sending out the rest of their acceptances before april 1? a girl can dream!
I also applied to Edinboro and Clarion. Edinboro was on spring break last week, so I'm kind of expecting to hear back this week. Clarion, looking at the "results" page, seems to take quite a while to get back to people :/ Best of luck!!
